資料庫 '%1' 中的交易失敗，因為陳述式是在快照集隔離下執行，但交易並非在快照集隔離中啟動。除非交易最初是在快照集隔離等級下啟動的，否則交易啟動之後就無法將交易的隔離等級變更為快照集。

Transaction failed in database '%1' because the statement was run under snapshot isolation but the transaction did not start in snapshot isolation. You cannot change the isolation level of the transaction to snapshot after the transaction has started unless the transaction was originally started under snapshot isolation level.
